Tiana Jackson discovered the black bear cub in 2016 and called a rehabilitation centre in Smithers, B.C., that was willing to accept the animal.

An officer from the provincial Conservation Officer Service examined the cub, decided it could not be rehabilitated and euthanized the animal.

The Association for the Protection of Fur-Bearing Animals filed a complaint against the service on behalf of Jackson, arguing officers can kill wild animals only when they are likely to harm people, property, wildlife or habitat.

Senior officials of the conservation service dismissed the complaint and the B.C. courts turned down subsequent appeals, prompting the association to take its case to the Supreme Court.
